There really are too many variables for a combo to be of any use as a standard.
Every car wants something different.

Babyblue66,
When talking carbs there is no standard that would work for everyone.
Thats what this question is all about.WHAT WORKS FOR YOU.

There is more parts in a carb that effect how a engine runs then any other part on the car.
It's the most adjustable peice there is and as far as trying to tune a motor it's the biggest pay off when you get it right.
If i had to pick a subject that was more over looked as far as making power ,it is how the carb is set up to run with a given combination.
IF THE FASTEST RACERS ON HERE GOT TOGETHER WITH THE SLOWEST RACERS ,WHAT WOULD BE THE FIRST THING THEY WOULD DO TO THE SLOW RACERS CAR????? :scratch:

ADJUST THE TOTAL TIMING AND TUNE THE CARB.

I have seen more people pissed off at there engine for not performing the way it sould, and them blaming the parts they installed in it,when all along it's the carb and the total timing.

Idle circuit is too rich, you might consider increasing the IABs or decreasing the IFRs about .003" each (all 4). Thats if this is a 4 corner idling system, if its 2 corner, i'd make it 4 corner.

 

[skep419]

I tried putting wire in the IFRs did not help. Its not the stinky idle that bothers me. Its the popping from the exhaust/inconstant rpm at cruise speed that is bugging me.

I just got it out from storage Monday. Got the timing were it wants to be and have been playing with the carb. I forgot my vacuum gauge at home today so tomorrow I will check to see what the cruise vacuum is.

It has the stock 4.5 pv in.

I agree, also too little initial timing can make tuning a pain.
